Combining Distribution Models of Plants and Their Mutualists to Map Gaps in the Knowledge of Ecological Interactions

open access: yesDiversity and Distributions, Volume 31, Issue 10, October 2025.
ABSTRACT Aim The distribution of species relying on mutualistic partners for reproduction can be constrained by their partners' distribution. Nonetheless, biotic interactions are often overlooked when estimating the distributions of species (e.g., pollinators of a given plant and the proportion of them with their distribution modelled). In the Tropics,

Single locus complementary sex determination in Hymenoptera: an "unintelligent" design? [PDF]

open access: yes, 2006
The haplodiploid sex determining mechanism in Hymenoptera (males are haploid, females are diploid) has played an important role in the evolution of this insect order.

Pharmacophagy in insects: Ecological and evolutionary perspectives on the non‐nutritional use of plant specialized metabolites

open access: yesEntomologia Experimentalis et Applicata, Volume 173, Issue 7, Page 661-673, July 2025.
Insects interact with plants not only for nutrition but also to actively seek plant specialized metabolites (PSMs) for chemical defense, reproduction, and self‐medication—a behavior known as pharmacophagy. This review examines how insects across diverse orders acquire PSMs from both food and non‐food plants for non‐nutritional benefits.
